Versa 4 won't update and it won't sync either

[bemark]

I just got my fitbit versa 4 yesterday.  When I set it up it, it looks like it loaded everything correctly, but the 'update tracker' button is still showing. When I push that button, it tries loading the update but takes a long time and then seems to time out. Also, the phone will not sync.

I have tried:

1. Deleting and reinstalling the app
2. Factory resetting the tracker
3. Powering off my phone and restarting

Is this a tracker issue or something else? Should I try exchanging the tracker?

I have an iphone 11 if that makes a difference. I appreciate any help!
